P0976 – Shift Solenoid B Control Circuit Low: Symptoms, Causes, Diagnosis & Repair Cost (2026 Guide)

P0976

Last updated:

Overview

The control module stored P0976 because it detected a problem with: Shift Solenoid B Control Circuit Low.

P0976 relates to Shift Solenoid B Control Circuit Low. Use a quality scan tool, follow wiring diagrams for your vehicle, and confirm tests before replacing expensive parts.

What does the P0976 code mean?

When P0976 is set, the vehicle’s diagnostics detected an issue described as: Shift Solenoid B Control Circuit Low. In practice, the ECM/PCM (and related modules) compare sensor inputs, commanded outputs, and self-tests for that subsystem. The exact repair depends on whether the fault is wiring-related, component-related, or a rationality/performance issue for this circuit or system.

Common symptoms of P0976

  • Transmission warning indicator
  • Harsh or delayed shifting
  • Slipping or flaring
  • Limp mode or limited gears
  • Poor acceleration
  • Check engine light

Possible causes

  • Fault affecting Shift Solenoid B Control Circuit Low (wiring, connector, or component)
  • Damaged sensor or actuator internal fault
  • Short-to-ground or bias low on the signal circuit
  • Reference voltage or ground issue
  • Control module or software calibration issue (less common—verify tests first)
  • Past repairs or aftermarket parts causing out-of-spec operation

How to diagnose P0976

  1. Scan for P0976 and review freeze frame / pending codes for related faults
  2. Inspect connectors and wiring related to: Shift Solenoid B Control Circuit Low
  3. Compare live data and commanded vs actual values for the affected system (per service information)
  4. Perform circuit tests appropriate to the fault type (continuity, voltage, resistance) before replacing parts
  5. Confirm power and ground integrity at the relevant module or sensor
  6. After repair, clear DTCs and verify under the conditions that originally set P0976

Tip: Use a scan tool that shows live data and freeze frame for the conditions when the code set.

Severity of code P0976

Moderate: Have this code diagnosed soon; ignoring it can lead to worse fuel economy, repeat failures, or secondary damage.

Can you drive with P0976?

Short trips may be okay if the vehicle feels normal, but have it diagnosed—especially if performance, safety warnings, or overheating are present.

Avoid heavy acceleration, towing, or long highway drives until the cause of P0976 is confirmed and repaired.

How to fix it (step-by-step)

  1. Start with visual inspection and connector cleaning/tightening where needed
  2. Confirm failure mode with testing—avoid swapping parts without evidence
  3. Repair wiring or replace the failed component per manufacturer procedure
  4. Clear faults, run relearns if required, and road test to confirm

Repair & fix options

  • Replace failed sensor/actuator if confirmed
  • Locate and repair short-to-ground
  • Verify reference voltage and grounds
  • Clear codes and verify repair with a drive cycle and readiness where applicable
  • Reinspect related monitors if the code returns after repair

Typical repair cost

$150 – $4,500+ depending on cause

Estimated cost breakdown for P0976
Repair type Typical range
Fluid And Filter Change $150 – $450
Solenoid Replacement $350 – $1,800
Speed Sensor Or Internal $900 – $2,800
Transmission Rebuild Or Replace $1,500 – $4,500+

How to help prevent P0976 in the future

  • Fix new codes early before secondary damage or catalyst stress
  • Keep connectors clean and secure; address rodent or water intrusion in harnesses
  • Use the correct fluids/parts for your vehicle and service intervals
  • Avoid ignoring pending codes after battery work or repairs

When to see a mechanic

Schedule diagnosis if the check engine light is on, drivability is worse, or you notice new noises, smells, or warning lamps. For safety-related (SRS/ABS) or overheating symptoms, prioritize a qualified shop immediately.

Common mistakes when diagnosing P0976

  • Replacing sensors/modules without verifying wiring and reference voltages
  • Ignoring related codes that identify the real root cause
  • Clearing codes without a verification drive cycle

Common vehicles & notes for P0976

  • Ford / Chevrolet models (common examples—verify for your vehicle)
  • Toyota / Honda applications vary by engine and model year
  • Many other makes—this is a standardized OBD-II definition: Shift Solenoid B Control Circuit Low

P0976 is reported across many platforms including Ford, Chevrolet, Toyota, Honda. Always use VIN-specific service information for testing limits and calibration steps.

Frequently asked questions

What does P0976 mean?

P0976 indicates a fault involving Shift Solenoid B Control Circuit Low, based on what the control module detected during self-tests or live monitoring.

Is it safe to drive with P0976?

If the vehicle runs normally and no warning lights are flashing, short trips may be reasonable—but avoid ignoring symptoms like misfire, overheating, ABS/SRS warnings, or major loss of power.

How much does it cost to fix P0976?

Typical repairs often fall in the ranges shown on this page, but final cost depends on labor rate, parts quality, and whether the issue is wiring vs. a major component.

What is the most common cause of P0976?

Most shops start with wiring/connectors and the directly monitored component for “Shift Solenoid B Control Circuit Low,” then expand testing if the fault returns.

Will P0976 clear itself?

It may become intermittent, but if the underlying fault remains, the code will usually return—especially after a drive cycle.

Can a weak battery cause P0976?

Low system voltage can cause odd sensor/module behavior, but you should still validate the actual DTC and perform normal circuit/component tests.
